When the first beep occurred, he would then know if the level was correct. If the level was not at the desired point, the user would have to retry the volume procedure, entering a different volume number. This sequence was continued until the desired level was reached. It is desirable to have a

Abstract

Une interface utilisateur permet de simplifier le réglage de volume concernant un haut-parleur et celui de l'économie d'énergie relatifs à un système informatique. L'affichage d'une icône symbolise le réglage de volume du haut-parleur et englobe un graphique qui représente ce volume relatif. En appuyant sur les touches des flèches droite ou gauche, on modifie ce graphique et le volume du haut-parleur. Si on appuie sur la touche à flèche dirigée vers le bas alors qu'on règle le volume, le haut-parleur émet un bip permettant de vérifier simultanément ce processus. On recourt à une série d'icônes pour afficher et choisir un niveau d'économie d'énergie. Chaque icône comporte l'image d'une pile électrique à laquelle est accolé un robinet. Des débits d'eau différents symbolisent les différents niveaux d'économie. Une silhouette humaine adjacente au robinet indique le niveau d'économie choisi par l'usager.
